Point integrating bottle

  1. 1. 20.002 POINT INTEGRATING BOTTLE Approval Date: 20 May 1998 Reviewed on : 23 October 2007 Version: 1 Equipment Specification: POINT INTEGRATING BOTTLE Version 1 20.002-1/2 Purpose The suspended sediment sampler is for manually taking of point integrated samples in rivers, canals and reservoirs. Introduction The bottle sampler is a point-integrating device. The current practice in most states of the Indian Peninsula is to use the “Punjab” bottle sampler for measuring suspended load. The sampler is designed for rivers with suspended load almost exclusively composed of wash load, with no or little coarse and medium particle size fractions. The measurement procedure with this instrument is described in several documents, though no real standard procedure seems to be adopted. There are no clear or uniform guidelines for adopting one or another procedure on the basis of the flow and the sediment characteristics of the river at the measurement section. Conditions & Requirements • The sampler shall have a streamlined body. • No bolts or other parts, other then for taking the sample, shall protrude from the body. • The sample shall remain intact while hoisting the sampler. • The sampler shall have a well established and proven correction factor. • Spares and tools required for routine maintenance shall be part of the delivery. • The standard list of spare parts needed for one year operation shall be listed and quotation given. A wading rod, designed to hold the hand-held sampler at the required sampling depth. Specifications water velocity up to 1.5 m/s water depth up to 2.5 m operation manually unmeasured depth 0.10 m maximum sampling distance from the bottom mass (without sample) 5 kg max Wading rod purpose to submerse the sampler to the required depth diameter 0.02 to 0.03 m length 2.5 m container holder at lower end Cork control by handgrip Features • Rigid sample container, easily replaceable
